Re: [osg-users] Best practice for getting OpenGL information ( Vendor, driver version etc)
Be advised that the information you get back from these queries is implementation dependent. If you have a system with multiple graphics cards, and they are different models or even from different manufacturers, you'd need to open a context on each and do multiple queries in order to collect a complete set of information. OK it's a holiday.

[osg-users] Best practice for getting OpenGL information ( Vendor, driver version etc)
I wanted to capture/print out the current OpenGL version, vendor information and maybe driver version at program startup. The glGetString() functions and osg equivalents require an active GL context. Would one create a special invisible context just to get this information?. Seems like this should be quite straightforward but forum/example searching didn't seem to turn anything up for me...

Re: [osg-users] Best practice for getting OpenGL information ( Vendor, driver version etc)
You need a glcontext to query the openGL - because it's possible that some supported features might depend on the configuration at runtime. I couldn't find an OSG specific exampel , but this might help http://stackoverflow.com/questions/126028/how-to-write-an-installer-that-checks-for-opengl-support Martin -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=21840#21840 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
